Description
Ursolic acid has many pharmacological actions including the antioxidant, anti-inflammatory, antibacterial properties according to studies and researches.
Many studies in the cosmetic industry have shown that ursolic acid stimulates collagen production in fibroblasts and improves the formation of ceramide in human skin and epidermal keratinocytes
Ursolic acid has traditionally been used for the skin as it repairs damaged tissues in the cutaneous barrier and scalp. It also protects the skin from photo-ageing and is a potent inhibitor of elastase, an enzyme present in the skin which attacks structural proteins. With its multiple properties, ursolic acid is therefore an important addition to the range of phytoceutical resources available for helping fight signs of age in general.
